ABSTRACT:
A processor implemented prosthodontia system employs digital imaging of a restoration site and surrounding areas of an oral cavity and digital sampling of colorimetric values of tooth surfaces. The processor selects digital image data representative of a tooth surface configuration corresponding to the tooth number of the tooth to be restored and generates a three dimensional image of the restoration, with colorimetric values. Data comprising the shape and colorimetric values of the restoration is transmitted to a fabrication station for processor controlled fabrication through implementation of, for example, a three dimensional jet printing system employing particulate porcelain, polymeric dental composite, etc., and a binder, solvent or reactant and which builds a preform in successive layers of incremental cross sectional heighths. The shaped and colored preform is then hardened to produce a restoration having the specified size, shape and colorimetric values.
